Bike brush for bicycles. Durable construction. Sturdy bristles that quickly remove dirt from even the dirtiest chains. Ergonomically shaped for comfort and stability. The long brush end is ideal for wiping away dirt and grime from drivetrain components. Suitable for most chain sizes and types. The Muc-Off bike chain brush is an essential tool for keeping your bike's chain and entire drivetrain spotless and running smoothly. The multifaceted, ergonomically designed brush is engineered to clean three sides of the chain at once. Its bristles and rollers allow for a deeper clean, helping to keep your chain in optimal condition for longer. The longer bristles at the end can be used to clean other drivetrain components, such as chainrings, cassettes, and jockey wheels. Instructions: 1. For best results, apply Muc-Off drivetrain or chain cleaner or degreaser and agitate with the drivetrain brush. 2. Mix the entire chain and regularly apply more of your chosen formula. 3. Rinse thoroughly with water and apply a water-displacing spray. 4. Wipe away any residue with a cloth and finish by applying a Muc-Off chain lubricant of your choice for the best and longest-lasting results. 5. To maintain the performance of all brushes, avoid using them with boiling water and in hot areas. We recommend using warm water.
